PATENTOFFICE PROTECTIVE GOGGLES Samuel E. Bouchard, Rochester, N. Y., assignor to .Bausch &.Lomb Optical Company, Rochester, N. Y., a corporation of New York Application June 16, 1938, Serial No. 214,102

4 Claims. (01. 2-14 The present invention relates to goggles and more particularly to ventilated protective goggles.

One of the objects ofthe'present invention is to provide ventilated protective goggles which are simple and inexpensive in construction yet rugged and efficient in use. Another object is to provide goggles which are well ventilated and yet afford ample protection against both mechanical injuries and harmful radiations. A further object is to provide goggles having a simple but effective protective shield secured within each eyecup. These and other objects'and advantages reside in certain novel features of construction, arrangement and combination of parts as will hereinafter be more fully set forth and pointed out in the appended claims.

Referring to the drawing:

Fig. 1 is a front elevation of a pair of goggles embodying my invention.

20 Fig. 2 is a section taken on line 22 of Fig. 3.

Fig. 3 is a section taken on line 33 of Fig. 2.

Fig. 4 is an elevation of the bridge anchoring socket.

Fig. 5 is a fragmentary side elevation of one of 25 the eyecups.

A preferred embodiment of my invention is illustrated in the drawing wherein is illustrated a pair of goggles consisting of two eyecups l and I I, connected by a bridge designated generally at 30 I2. These goggles are retained on the head by a suitable head band I3. The two eyecups I0 and II are substantially identical so only one will be described.

As shown in Figs. 2 and 3, the eyecup I0 is 35 roughly cylindrical in shape. One edge of the eyecup I0 is slightly flanged outward and shaped to fit the contour of the face adjacent the eye while the other edge is a fiat, lens-receiving surface. A large ventilating opening I4 is formed 40 in the temporal side of the eyecup II] and a screen I secured to the eyecup by rivets I6 covers the opening I4 to prevent the entry of foreign particles. A projection I1 secured to the screen I5 extends through the opening I4 adjacent the 45 face engaging edge to secure the screen I5 rigidly to the eyecup Ill. The screen l5 has a rearwardly extending lip l5 which is perforated at I8 to receive the head band l3. A suitable enlarged tip I 9 prevents removal of the head band I3.

50 Within the eyecup I0 is a cylindrical inner cup 20. When it is desired to protect the eye from radiations as well as foreign particles, this inner cup may be made of a suitable opaque material such as paper or fiber, for example. Secured to 65 the inner cup by rivets 2| is a clip or projection 22 which engages the edge of the opening I4 adjacent the face engaging edge of the eyecup I 0. Suitable .projections'23 on the inner cup 20 engage'the inner wall of the eyecup I 0 and hold the two 'cups I0 and 20 in spaced relation so as to provide an air passage between the cups.

At the nasal side, the inner cup 20 has a plate 24, preferably of metal, which is provided with an aperture 25 in alignment with an aperture 26 in 10 the eyecup II]. A socket member 21 of cylindrical form is secured in these apertures 25 and 26 and held against removal by a flange 28 at its rear end. The front end of the socket member has a keyhole-shaped opening 29 for receiving the bridge member I2 which is preferably formed as a series of balls 30 connected by links 3 I. The large part of the opening 29 will readily pass the balls 30 while the small part will admit only the links 3I and thus hold the balls 30 against removal. The balls 30 and links 3I are preferably covered 20 with a tube 32 of soft material such as rubber.

A suitable lens 33 is mounted on the lens-receiving front edge of the eyecup I0 and engages the front edge of the inner cup 20. This front edge of the cup 20 is provided with cut away depressions 34 to permit the passage of air from the space between the two cups to the space within the inner cup 20.

In order to improve the ventilation of the goggles, the eyecup I0 is provided with a series of 30 radial apertures 38 which are located below the edge of the cap ring 31 and open into the space between the eyecup I0 and the inner cup 20. These apertures 38 are preferably small so as to prevent the entrance of dirt or other particles into the eyecup II].

The lens. 33 is preferably colored to absorb any glare or harmful radiation. A second lens in alignment with the lens 33 and spaced therefrom by a washer 36, is preferably formed of hardened 40 glass to protect the inner lens 33 from mechanical blows. The two lenses 33 and 35 are secured on the eyecup I0 by a cap ring 31 which is threaded onto the eyecup ID. The threaded portion of this cap ring 31 extends along the side of the eyecup I0 past the large part of the opening 29 in the socket member 21 and thus serves to lock the bridge I2 in the socket member 21.

From the foregoing it will be apparent that I am able to attain the objects of my invention and provide a new and improved goggle which is simple, inexpensive, rugged and eflicient. The particular goggle described is particularly adapted for protection against both harmful radiation and mechanical blows and the particular lenses and material of the inner cup were chosen for this purpose. For other purposes other selections could readily be made without departing from the spirit of my invention or the scope of the appended claims.

I claim:

1. In a pair of goggles an eyecup having one edge shaped to fit the face of the wearer and the other edge shaped to receive a lens, said eyecup having an opening through the temporal side, an inner cup adapted to fit Within said eyecup in spaced relation therewith, positioning means secured on said inner-cup for engaging the edge of the opening in the eyecup, said cups being provided with aligned apertures through their nasal sides, a socket member extending through said apertures, and means on said socket member for detachably retaining a bridge member.

2. In a pair of goggles an eyecup having one edge shaped to fit the wearer and the other edge shaped to receive a lens, said eyecup having an opening along the temporal side thereof, a perforated shield secured on said eyecup over said opening, an inner cup'adapted to fit within said eyecup, a stop secured to said inner cup for engagement with the edge of said opening to position said inner cup in said eyecup, means on said inner cup for engaging the eyecup to hold the inner cup in spaced relation to said eyecup, said cups having aligned apertures through their nasal sides, a socket member within said apertures and means on said socket member 'for detachably retaining a bridge member.

3. In a pair of goggles an eyecup having one edge shaped to fit the face of a wearer and the other edge shaped to receive a lens, said eyecup having an opening in the temporal side, a perforated screen secured to said eyecup and covering said opening, an inner cup adapted to fit within said eyecup, means on said inner cup for engaging the edge of said opening to position said inner cup, means for holding said inner cup in spaced relation to said eyecup, said cups being provided with aligned apertures in their nasal sides, a socket member in said apertures, means in said socket member for retaining a bridge member, a lens adapted to rest on the lens-receiving edge and engaging the edge of said inner member, said edge of said inner member being cut away to provide air passages, and means for securing said lens on the lens-receiving edge.

4. In a pair of goggles an eyecup having one edge shaped to fit the face of the wearer and the other edge shaped to receive a lens, said eyecup having a ventilating opening in its temporal wall, an inner'oup smaller than the eyecup and positioned within said eyecup, means on said inner cup for engaging a wall of said aperture to secure the temporal side of said inner cup within said eyecup, said eyecup having an opening through its nasal wall, a socket member positioned in said opening, means on said socket mem her for detachably retaining a bridge member and means on said socket member engaging the nasal wall of the inner cup to retain said inner cup within said eyecup.
